有人能告诉我我能做什么吗？它告诉我，我无法将 _videoViewerWPF.SetImageProvider(_provider) 行从 Ozeki.Media.BitmapSourceProvider 转换为 Ozeki.Media.IImageProvider，我完全不知道该怎么做才能起作用。

我尝试了几次做某事，但我什至不知道我在做什么。如果有人可以帮助我，我会很感激，所以我可以完成这个。

在遵循 Ozeki 视频C# 相机教程 #3 - YouTube 上的相机查看器后，我遇到了同样的问题。

可能是因为 Ozeki 网站上的示例代码（如何连接到 RTSP 相机并在 C# 中显示图片）上的示例代码使用了 DrawingImageProvider 而不是 BitmapSourceProvider：

...

private DrawingImageProvider _provider = new DrawingImageProvider();

...

...然后（对于 WPF 应用程序）：

_videoViewerWpf.SetImageProvider(_provider);

就我而言，这修复了编译器错误，我现在可以在 WPF 应用程序中显示 RTSP 视频。
